Application filed February 3, 1893. Serial No. 460,898- (No model.)

.To all whom it may concern.-

Be it known that 1, JOHN H. DAVIS, a citizen of the United States, and aresident of the city of Cincinnati, in the county of Hamilton and Stateof Ohio, have invented certain new and useful Improvements inSlot-Machines for Delivering Liquids, of which the followingis aspecification.

The several features of my invention and the various advantagesresulting therefrom will be fully apparent from the followingdescription and claims.

In the accompanying drawings making a part of this specification, and towhich reference is hereby made, Figure 1 is a vertical central sectionofa machine illustrating my invention, taken from front to rear, certainparts of the device being in elevation. Fig. 2 is an elevation of a partof the delivery tube and of the valve, and the mechanism for immediatelyactuating it,the elevation being f the same side as that shown inFig. 1. Fig.

3 is a top view of the devices shown in Fig. 2, and of the pawl andplate for receiving the coin. Fig. 4: is an elevation of the oppositeside of the devices shown in Figs. 1 and 2, from thatshown in saidfigures. Fig. 5 is a vertical transverse section of the valvecontrolling the egress of liquid from the machine. Fig. 6 is amodification of apart of the immediate devices for actuating the valve.Fig. 7 is a mode of exchanging a weight for a spring as the motivepower. Fig.8 isa side (detail) elevation of the tube whereby the coin isconveyed from the point where it enters the casing to the mechanismwithin the latter, hereinafter described. Fig. 9 is a view, in detail,of the pawl and the weight as adjustable thereon.

A indicates a casing, having a bottom A, sides A and top A The latter isremovable at the will of the owner of the machine, being locked to thecasing by a suitable lock, of which the owner has the key. Within thecasing is a vessel, '11. e. reservoir B, for the reception of the liquidto be subsequently dealt out by the machine.

A convenient and econom cal mode of supporting the reservoir B is shownand consists in bending over the sides of the casing and uniting them tothe upper end of the latter. In the lower part of the'reservoir B is anopening B, connected to the delivery tube C. The latter is continuedthrough the space in the casing, and passes through the casing andterminates outside of the latter in the spout C it being understood thatno portion of the tube C is higher than the point where it takes theliquid in the reservoir B. The tube is preferably shaped and located asshown. In the tube, near the reservoir B is a stop cock C, whichentirely controls theflow of liquid from the reservoir B through thetube 0. At

cock and the side of the casing through which the tube passes out, islocated a cock D, a preferred form of which is the one shown in Fig. 5and which when turned a given distance, cuts off the flow of liquidthrough the said tube, and which when further operated, allows theliquid to pass through it. A motor is present to operate the valve, andthe preferred description of motor consists of the spring E, wound onand fixed at one end to spindle E, journaled in frames S, S, the otherend of the spring being fastened to the frame S. On the spindle E isfixed a pinion or gear wheel E, which meshes with a pinion or gear wheelG, rotating on a suitable shaft G,'and this latter wheel G in turnmeshes with the pinion or gear wheel H, rigidly fixed on the shaft H,supported in a suitable frame piece as S. One end of this shaft isconcentrically fixed to one side of the valve D, so that the latter mustrotate with the shaft. Con nected concentrically to these last nameddevices, and preferably at the other side of the tube C, is a ratchet ornotched wheel I, containing one or more teeth or notches I. A pawl Jpivoted at J to a suitable support (in the present instance upheld. 'bythe casing) is arranged so. that its free end rests upon the peripheryof the wheel I, and as the latter revolves enters the notch I. This pawlis connected to a plate K, extending out on that side of the pivotopposite where the pawl J is located.

The coin for setting the machine in opera- In the casing is a slot L ofa size sufficient to admit the coin which is to operate the machine. Theslot opens to a tube M, straight for a given distance and then continuedat a different angle, and after a given distance a suitable point in thetube C between the tion falls upon the portion K of the plate K;

again continued at a another angle. Thus the tube M is crooked, andconsists of the three straight lengths M, M and M The object of makingthe tube thus crooked is to prevent boys, or others, from introducing astick or wire through the slot L, and depressing the plate K andoperating the machine. The crooked path of the tube prevents the wirebeing successfully inserted as far as the plate K. The lengths M, M andM of the tube M are enlarged in order that in case a wad or piece ofpaper is stuffed through the slot L, into the tube M, it will fallthrough the tube and pass off the plate K with the coin next introducedinto said tube.

The tube M is perforated and the portions perforated are the lengths Mand M These perforations M are for preventing a person from operatingthe machine by blowing into the tube, and thereby depressing the plateK. The size and number of these perforations are to be sufficient toaccomplish this object. The perforations are also for catching the wireor stick poked in through the slot L, and preventing the wire or stickfrom reaching the plate K.

The spaces S are usually present between the casing and the reservoir B,and will ordinarily be to a greater extent packed or filled with asubstance whereby the temperature of the liquids in the reservoir willnot be subject to the temperature of the air outside of the casing. Inother words, if a hot liquid as coffee is in the reservoir, it will notbe cooled by the atmosphere without the casing, and if ice cool lemonadebe the liquid in the reservoir, this liquid will not be warmed'by theatmosphere outside of the casing.

The mode in which my machine operates is substantially as followsz-Thereservoir B is filled with the desired liquid. The pawl is in the notchI of the wheel I, and the cock is closed. The cock 0 is opened and theliquid fills that portion of the pipe between said cock 0 and the cockD. The cover A is now put in place on the casing, and locked there. Themachine is now ready for operation. The person desiring to obtain a cupof the liquid from the machine, places the requisite coin in the slot.The coin descends through the tube M and falls onto the portion K ofplate K. The weight of the coin causes the end K to descend and liftsthe pawl out of engagement with the notch in the wheel I. The spring Eis thereby permitted to act, and it turns the gear F, and thereby gear Gis turned, and by the latter the gear H is turned, thereby graduallyrotating the cock D. As the latter turns, it allows the liquid to flowpast it and through the delivery end of the pipe. The liquid thus flowsfrom delivery spout 0 into a cup or glass held beneath. As soon as thepawl I ascended, the plate K dropped, and the coin slid therefrom, andfell into a receptacle within the machine. The pawl I being heavier thanplate K, then descended and its free end travels over and on theperiphery of the wheelI, in readiness to drop into notch I as soon asthe latter shall reach it. As the cock continues to turn, it willshortly shut and again open the tube, and when the wheel I has made ahalf revolution, the pawl J will engage the notch I and stop the wheel Ifrom further movement. The amount of liquid thus delivered through thetube 0 in exchange for the coin given to the machine, will fill a cup ofa given size and preferably chained to the machine.

The amount of liquid to be delivered can be regulated by the strength ofthe spring, or the number and size of the gear introduced, or by thenumber of notches on the wheel I. A very convenient mode of regulatingwithin certain limits the amount of liquid delivered is by turning thecock 0' more or less, thus allowing a greater or less amount of liquidfrom the reservoirto be supplied to the tube in a given time.

A modified means of controlling the delivery of liquid through tube 0 isshown in Fig.

6, and consists of the sliding valve D taking the place of the rotaryvalve or cock D, and having a stem provided with a rack D meshingwiththe sector gear H fixed on the shaft G, after the manner shown in Fig.6. As the gear G revolves, the sector H engages the rack D and lifts thesliding valve D, and then leaves the rack, whereupon the spring D drawsdown said valve D, and shuts off the flow of liquid.

When desired,a weight E a pulley E cord E and drum E may be substitutedfor the motor (spring E), substantially as shown in Fig. 7.

When it is desired to greatly retard the revolution of the wheel I, andconsequently to retard the delivery of liquid from the tube 0, the gearmay be provided with a governor or clock escapement, or a rotary fan, inany of the Well known forms and modes.

Persons (usually children) are fond of putting various things such aschewing gum, buttons, 850., through the slot L and into the tube M. Inorder to enable the tube to be quickly and thoroughly cleaned, I make itopen, that is to say there is a slot in the tube on one or both sides asdesired. In the present instance, the slot L is vertical and the tube Mwill, in cross section, also be deeper from top to bottom than from sideto side, and the slots M are in said sides. If the entrance slot L ishorizontal, the flattened tube will be correspondingly turned, and inthis case the slots will also be in the widened portions.

Should the tube become dirty, or should anything stop in it, the dirt orobstruction can be removed by a wire passed through the adjacent slotand across the tube and carried up and down, at right angles to thetube.

Access to the interior of the casing may be had by any suitable means.For example, N indicates a door in the casing hinged at N, and securelyheld shut by a lock N When this door is open, access is had to the cock0,

to the mechanism whereby the cock for doling out liquid, is operated bya coin introduced through slot L. Thus also the cash dropped by plate Kcan be reached and removed, the tube M cleaned, &c. I have adapted themachine, so that a coin of a given denomination can be used therein.Inasmuch as the coins differ not only in size, but in weight, Irearrange the weight of the pawl so as to be readily and properly liftedby the weight of the given coin falling upon the plate K. I accomplishthis by a balance or weight, carried by the pawl and adjustable alongit, and capable of being fixed at a desired point thereon. Onedescription of such a device is shown in Fig. 9, and consists of aweight P, having a yoke P, embracing the pawl. A spring P of the weightfits into any one of a series of notches present on the pawl, and aspring of the weight will as the weight is moved along engage a givennotch J there being one notch for each denomination of coin intended tobe used in the machine.

What I claim as new and of my invention, and desire to secure by LettersPatent, is

1. The rotatable cock and a wheel connected thereto, the wheel beingconcentric with the said cock and arranged to rotate in a forwarddirection only, and a motor mechanism combined therewith forautomatically compelling the cock to rotate forward, when permitted soto do, and devices for enabling a coin when dropped into the machine toallow the wheel to rotate a given distance, and deliver a given quantityof liquid, substantially as and for the purposes specified.

2.
